DISK CULTIVATOR.

To all whom 'it may concern.'

a citizen of the United States, residing at Rockford, in the county of IVinnebago and State of Illinois, have invented certain new and useful Improvements in Disk Cultivators, of which the following is a specification.

The object of this invention is a disk gang to be supported by a cultivator in which the disks are capable of being reversed also oscillated on a horizontal pivot.

In the accompanying drawings, Figure 1 is a side elevation. Fig. 2 is a rear elevato construct tion. Fig. 3 is a plan view. Fig. 4 is a the supporting frame of the cultivator section on line (L a Fig. 3.

In the drawings 1 have shown my im provements in connection with a beam of a cultivator and have not deemed it. necessary to show the cultivator complete as the connection of the beam at its forward end to may beaccomplished in various manners. The beaml 1 in this instance is tubular and has a transverse opening 2- at its forward end which receives the tubular transverse lsleeve 3 adapted to be supported by the 4frame of a cultivator. A set screw 4 connects the beam with thev sleeve in a-n adjustable manner. The rear end of the beam 1 is closed andl is formed with a hole through which a bolt 6 is inserted. A projection 7 is located near the rear end of the beam and extends upward therefrom. To this projection is secured a segment 8 by the bolt 9 and said segment is provided with a series of holes 10. At the rear end of the beam is secured a bracket 11 by the bolt 6 extending through it and held in place by the nut 12. From this bracket extends an arm lfwhich lies against the underface of the beam, and its forward end is clamped to the beam by the U bolt 14. From the bracket extends an extension 15 which supports a spring actuated plunger 16 at its upper end, and which.- is adapted to enter the holes 10 in the segment 8 which will form a connection between the bracket and beam inv a manner to allow of the oscillation of the bracket on the bolt as a pivot. From the bracket 11 depends a' sleeve 17, and from this bracket extend two wings 18 and- 19 to which are connected the curved arms'20 and 21 re- SPeCfvcly each of which is formed with Specification of Letters Patent.

holes 22. The disks 23 are supported by the boxes 24 to which are connected two pipe sections 25 and 26 having their upper. ends closed by the screw-threaded caps 27. The upper ends of these pipe sections are 6o connected by a bar 28 and clamped in connection therewith by the bolts 29. The said pipe sections and bar constitute in effect a 'disk carrier. The pipe section 25 is located in the sleeve 17 and the bolts 30 clamp 65 the sleeve around the pipe section in a manner to allow of the oscillation of the pipe section therein. A loop 31 depends from the underface of t-he bar 28' near the pipe section 26 and receives one of the wings 70 20 or 21. A spring actuated -plunger 82V is supported by the bar 28 and is adapted to enter the holes 22 in the wings 2O or 21. The bar. 28 is formed with a hole 33 which receives a stud 34 extending from the yoke 75 35 and a setscrew 36 holds the stud in connection with the bar. The yoke 35 supports a scraper bar 37 which is capable of a re` ciprocating movement in connection therewith. To the bar 87 are secured Scrapers 80 38 which are located to cont-act with the concave faces of the disks 23. A spring 39 is coiled around the scraper bar 87 one end resting against the yoke 35'and its other end against one of the scrapers 38. A cam lever 4() is pivoted to the scraper bar and is 1ocated to rest in contact with the yoke 35. By a movement of the cam lever the Scrapers can be held free of the disks and when the cam lever is released, the spring 39 will 90 force the Scrapers into contact with the disks. The bracket supporting the disks can be rocked on the horizontal axis and held by the spring actuated plunger 16, so as to level the disks or hold them in a tipped position. By releasing the spring actuated plunger 32 the faces of the disks can be reversed so as to turn the earth in the opposite direction and the angle at which they are held is regulated by the series of holes 22 receiving the plunger 32. When the position of the disks is changed, the yoke 35 carrying the scraper bar and Scrapers will be changed to the other face; of the bar 28.
